The problem appears to be leverage. I have no exposed shaft at all. But
the force while climbing stairs still managed to snap the axle at the pivot
point. I was suprised the axle broke and the retainers did not just pop off.
A steerable shrimp is a challenge. Keeping the structure strong is a
continual challenge. Also the number of motors keeps things interesting
also. I have not figured out that part yet. I need at least one more
output than I have. I will research motor controllers shortly.
